Oil Fired Models - Fuel Supply

Kerosene Models (2, 3 and 4 Oven)

There are a number of important points to consider regarding the fuel supply.

Storage tank.
These may be constructed of steel or plastic, to the relevant OFTEC standard. An ideal capacity is 1400 litres (300gallons)

The tank must be sited in accordance with current regulations so as to minimise the risk of fire or fuel spillage. Refer to OFTEC guide sheet T131 for further information.

The fuel must flow by gravity to the Aga, therefore the tank must be sited at a higher level than the cooker, with the base of the oil tank not less than 450mm above the base of the Aga, but the top of the oil tank not higher than 3.2m above the base of the Aga (2 and 4 oven models or 600mm for 3 oven models). The top of the oil tank must not be higher than 3.2 metre above the base of the Aga. Only a bottom outlet tank must be used.

If the tank cannot be sited higher than the Aga, then as a last resort, a proprietary ‘Oil lifting’ device can be used, but this introduces essential dependence on electricity for the Aga operation. De-aeration devices, ‘Tiger Loops’ or 2 pipe systems cannot be used with an Aga.

Fuel Pipe.
This should be of at least 10mm diameter, preferably of soft, plastic coated copper, suitably protected where underground. A steady fall from the tank to the Aga is desirable, to avoid air locks. Sharing the oil supply pipe with another oil appliance is not recommended.

Filter.
A strainer/filter should be fitted at the oil tank, together with a contents gauge and service valve. An additional 5- 10 micron filter is fitted adjacent to the Aga.

Fire-valve.
A fire valve must be fitted at the point where the fuel line enters the property, with its sensor inside the property, to isolate the fuel in the event of a property fire. A second fire-valve is fitted adjacent to the Aga, with its sensor located inside the burner housing, to detect any malfunction in that area. Both fire-valves should be rated at 66 deg.C

Fuel.
The kerosene oil fired Aga is designed to burn Commercial grade Kerosene, Class C2, complying to B.S 2869 Part 2, suitable for vapourising burners.

GasOil (Diesel) is not suitable.
